TR3031X series is the 1 universal oscilloscope current probe, compatible with more than 95% of oscilloscopes on the market, with a frequency response measurement range of 50mA to 100A (peak value) up to 5MHZ, and BNC output terminals. Connect an oscilloscope to accurately measure AC or DC current waveforms, with a selectable range on the handle panel; the current probe detects the current flowing through the conductor and converts it into a voltage that can be seen and measured on the oscilloscope. The current probe uses a hybrid technology including a Hall effect sensor (sensing DC current) and a current transformer (sensing AC current). The open design current probe is easy to connect and disconnect from the conductor, providing a DC to 5.5MHz measurement bandwidth.

AC/DC dual-useIt can be seamlessly compatible with mainstream oscilloscopes such as Keysight, Tektronix and Rhodes without additional adapters. The 5.5MHz ultra-wide frequency response accurately captures the details of transient signals such as motor start-stop surges and power ripple, which can achieve several times higher accuracy than traditional AC probes. It can perfectly solve the pain points of engineers such as high-frequency transient waveform distortion and complicated impedance matching of oscilloscopes in power electronic testing, helps to efficiently complete switching power supply debugging, motor control optimization and EMI fault diagnosis. At the same time supports DC component measurement. |
Double gear wide free switchingThe high sensitivity range is 100mV/A, with a safe range of 7A RMS, which can accurately meet the use requirements of small current scenarios such as consumer electronics and BMS chips, and provide reliable and sensitive measurement guarantee for these refined current applications. The high-load gear adopts a 10mV/A broadband Hall element, which can easily conquer industrial-grade large current and can carry a peak current of 100A, providing strong technical support for large current monitoring and control in the industrial field. It is widely applicable to various complex application scenarios with different requirements on current monitoring accuracy and load capacity without manual calibration. The gear switching response is less than 0.5 seconds, and zero offset is automatically eliminated, avoid the time-consuming operation that requires repeated zeroing of traditional probe shifts. |

Humanized operation designOne-key self-zero calibration (AUTO ZERO) technology, 3 seconds to automatically remove temperature drift and magnetic saturation, bid farewell to manual zero adjustment time-consuming; Double indicator light buzzer system-remind the risk of over-limit overload, 11.8mm industrial jaw design, compatible with motor cable and power bus, can directly clamp thick wires without disassembly. |
Dual mode power supplyUSB adapter (5V/2A) and 9V dry battery are used to completely solve the problem of power failure in harsh environments such as field operations and aerial operations. In the dry battery power supply mode, the equipment has a endurance of over 480 minutes (8 hours) and is durable and reliable. The unique dual-circuit isolation design ensures safe and pure power supply -- USB strongly suppresses 90% of mains noise interference during power supply, while the dry battery mode completely eliminates common mode interference, providing stable and noise-free power guarantee for precision instruments or key tasks in the field/high altitude, and eliminating power failure troubles. |
